tical installation standpoint,rit' is desirable that the latch membertoretain a rolling wlndow screeny in its withdrawn position be locatedagainstr the sill of the window and lyetcarried bythe track proper, andin Lorder sorto do, lprovijde a latch element, which is ofsubstantiallythe construction shown in Letters Patent, No.1,715,858,issued J une 4, 1929, to the RolscreenCompany, as assignee, Which deviceis capable of adjustment of the finest degreek or adjustmenty of a greatvariance, such adjustment being accom- 'plish'e'd bya pluralityofopenings formed in the latch member and the member` upon which Vthelatch is slidably mounted.

With these and other objects in view, my invention consists in theconstruction, Iarrangement and combination of the Various parts of myroll screen latch, whereby the objects contemplated are attained, ashereinafter more fully set forth, pointed out in my claims. andillustrated in the accompany- Figure 1y is a plan view "of a. portionlof a window frame together with a lower portion of arolling windowscreen with m-yimproved latch installed thereon.

The latch element thatI ,provide'is adapted to coact with the ledge 18for normally holding the screen in its withdrawn position. The sideedges of the screen 14 are adapted to travel in guide tracks 20, whichare mo'nnte` at 'attaching tlangeV 24 is adapted to restA kagainst theside jambsl() and to be `sec'iired' thereto by screws or they like 27.The screws project-through elongated slots 29 whereby adjnstment-'ofthetracks toward or from each other may bev accomplished.

My latchy element includesa resilientinern-V a ber Br-,arranged vincircumscribing. relation-x :ship tothe track 20.

A resilient'projection SOiscarried bythe bodyyofithe latch element, anda'lug'32 is 'formed thereon which coacts with the'lower ledge 18jofthe'binder 16.

order to provide for proper -adjnstment ot the latch element B upon thetrack20, I provide a seriesof spaced openings 84,!r upon1theiiatattaching'flange 24 of the track 20.`

Through' the two flanges28 of eachlatch element B, I likewise' provide aseries of'openings 3e. Y

The openings 34 are spaceda greater distance apart than are theopenings36, the purpose ofA which lwill Vbe hereinafter `more fully set forth. i
